DRIVING TUBE-WELLS.

SPECIFICATION forming part of Letters Patent No. 267,605, dated November 14, 1882,

Application filed May 4, 1882.

To all whom it may concern:

Be it known that 1, WILLIAM J. SHERMAN, a citizen of the United States, and a resident of St. Augustine, in the county of St. Johns and State of Florida, have invented a new and valuable Improvement in Driving Tube-VVells; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being bad to the annexed drawings, making a part of this specification, and to the letters and tigures of reference marked thereon.

Figurel of the drawings is a representation of this invention in perspective. Fig. 2 is a longitudinal section without the weight. Fig. 3 is a plan view of the slide-weight. Fig. 4is a cross-section =of the slide-weight, taken through one set of holes, in which is shown the removable pin.

This invention has relation to means for driving tube-wdlls; and it consists in the construction and novel arrangement of parts,:as will be hereinafter fully described, and particularly pointed out in the claim.

In the accompanying drawings, the letter d indicates the well-tube, and a the anvil-cap, which is recessed on the inside to admit the upper end of the tube. The cap is annularin form, consisting of a ring of iron or steel, and it is made with an internal bearing, a, nearits upper end, which engages the end of the tube. The cap thus forms an anvil-surface above the end of the tube and protects the same, preventing it from being battered by the impact of the drive-weight. Fitting loosely in the tube d is the guide-rode, which extends above the tube; and is provided with a swivel or bearing, g, at its upper end. The drive-weight b is a heavy casting, having a longitudinal central bearing,f, designed to fit looselyon the guide-rod c. This bearing f is made in slot torm, opening laterally, so as to be easily placed on the guide-rod when the latter is in (No model.)

| position. This recess-bearingfis designed to be closed in front by means ot'- transverse removable pinsh, passing through holes la in the weight, and serving to keep the weight onthe guide-rod c. The weightis provided with eyebolts 6 at its upper end, whereby it is lifted.

In operating this device the rod 0, having been arranged in the tube, is held or hung in vertical position by means of a rope or chain connecting its upper end to a transverse bar supported above it by any suitable frame- Work. eyebolts of the weight and running through the swivel-eye g of the rod, or over a pulley above the same, the weight can be lifted on the rod, and then, being allowed to fall,itwill drop forcibly on the anvil-cap a, and by itsimpact will force the tube into the ground acertain distance. By a repetition of the blows of the drive-weight the tube can be easily driven into the ground in vertical position.

A tube provided with a cap atits upper end, said cap having a rod extending upwardly therefrom and provided at its upper end with a disk to disengage a lifting-hook from the driving-weight which slides upon the rod, is old, and a construction of this kind is not claimed herein.

Having described this invention, What I claim, and desire to secure by Letters Patent, 1s

The combination, with the guide-rod c, having the swiveled ring 9, and the cap a, of the slide-weight I), having the eyes e, lateral slotbearing f, and removable transverse pins h, substantially as specified.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.
